USB Interface Data Acquisition System Hardware Design

Main research in this text is based on the USB's interface DA system hardware design. Base on knowing USB's chip correlation hardware information and USB protocol and DA systematic architectural structure and oneboard computer information queen, and a hardware development solution was come out in the design. This solution consists of the data acquisition module hardware development designs, and oneboard computer online programming circuit design, debug and oneboard computer data acquisition program development along with DA system together with USB's installation interface design and debug. Finally achieves the DA system by means of USB's interface together with the superordinate host computer speedily and without delay and the dependable data transmission.
